Description

Die Erfindung betrifft ein Haushaltsgerät, mit einem Magnetron, welches dazu eingerichtet ist, im Betrieb Mikrowellen zu erzeugen, einem Netzteil und einer Steuerung, welche dazu eingerichtet ist, dem Netzteil die Leistung für den Betrieb des Magnetrons vorzugeben.The invention relates to a household appliance with a magnetron which is set up to generate microwaves during operation, a power supply unit and a controller which is set up to specify the power for the operation of the magnetron to the power supply unit.

Ferner betrifft die Erfindung ein Verfahren zum Steuern des Betriebs eines Haushaltsgeräts, mit den Schritten: Erzeugen von Mikrowellen durch ein Magnetron des Haushaltsgeräts und Steuern der Leistung für den Betrieb des Magnetrons durch eine Steuerung des Haushaltsgeräts.The invention further relates to a method for controlling the operation of a household appliance, comprising the steps of: generating microwaves by means of a magnetron of the household appliance and controlling the power for the operation of the magnetron by controlling the household appliance.

Insbesondere betrifft die Erfindung eine adaptive Leistungssteuerung für Hausgeräte mit einer integrierten Mikrowelle sowie separate Mikrowellengeräte. Die Mikrowelle enthält einen Hochfrequenzgenerator im 2.4 GHz ISM-Band. Eine Variante besteht aus einem Magnetron, sowie einem Hochspannungsschaltnetzteil. Sie wird zur Erwärmung von Speisen mittels hochfrequenter Strahlung genutzt.In particular, the invention relates to an adaptive power control for household appliances with an integrated microwave and separate microwave appliances. The microwave contains a high frequency generator in the 2.4 GHz ISM band. A variant consists of a magnetron and a high-voltage switching power supply. It is used to heat food using high-frequency radiation.

Bei der Erwärmung werden mitunter sehr hohe Leistungen im Bereich von mehreren 100 W bis einigen 1000 W verwendet. Diese Leistung wird in Form von hochfrequenter Strahlung an das Gargut abgegeben. Parallel zu der Mikrowelle operieren im gleichen Frequenzband verschiedene Funknetzwerke, wie zum Beispiel WLAN (IEEE 802.11), Bluetooth oder ZigBee. Diese Funknetzwerke nutzen jedoch nur sehr geringe Sendeleistungen von maximal 100 mW, die um ein Vielfaches niedriger als die des Mikrowellengeräts sind. Dies hat zur Folge, dass das Funknetzwerk bei Betrieb des Mikrowellengeräts signifikant gestört werden kann, bis hin zum vollständigen Ausfall.When heating, very high powers in the range of several 100 W to several 1000 W are sometimes used. This power is delivered to the food in the form of high-frequency radiation. In parallel to the microwave, various radio networks operate in the same frequency band, such as WLAN (IEEE 802.11), Bluetooth or ZigBee. However, these radio networks use only very low transmission powers of a maximum of 100 mW, which are many times lower than that of the microwave oven. The result of this is that the radio network can be significantly disturbed when the microwave device is in operation, right up to complete failure.

Mit der Einführung vernetzter Geräte, der Steuerung über Smartphones und weiteren digitalen Anwendungen auf Basis von 2.4 GHz steigt die Praxisrelevanz dieser Störfälle. Durch den Mikrowellenbetrieb können sowohl eine WLAN-Station in dem Mikrowellengerät selbst als auch eine benachbarte WLAN-Station in einem anderen Gerät gestört werden. Das Problem kann für zwei Arten von Mikrowellengeräten noch besser skizziert werden.With the introduction of networked devices, control via smartphones and other digital applications based on 2.4 GHz, the practical relevance of these accidents is increasing. Microwave operation can disrupt both a WLAN station in the microwave device itself and an adjacent WLAN station in another device. The problem can be better outlined for two types of microwave ovens.

Wird die Mikrowelle mit einem Trafonetzteil betrieben, ist bei einer Netzspannung von 50 Hz die Hochfrequenzstrahlung für eine Zeitdauer von ca. 10 ms bei der positiven Halbwelle aktiv und danach für ca. 10 ms inaktiv. In der inaktiven Zeit kann ein WLAN-System oder allgemein 2.4 GHz-System Daten übertragen, da der Funkkanal nicht gestört ist. Der Durchsatz reduziert sich jedoch um 50%.If the microwave is operated with a transformer power supply, the high-frequency radiation is active for a period of approx. 10 ms with the positive half-wave at a mains voltage of 50 Hz and then inactive for approx. 10 ms. During the inactive period, a WLAN system or 2.4 GHz system transmit data since the radio channel is not disturbed. However, the throughput is reduced by 50%.

Der zweite viel kritischere Fall ist ein Mikrowellengerät mit einem Schaltnetzteil. Hierbei sind die Pausen deutlich kürzer. Zum Beispiel folgt auf ca. 8 ms Mikrowellenbetrieb eine kurze Pause von ca. 2 ms. Diese Pausen sind jedoch für manche WLAN-Access Points (AP) und WLAN-Stationen (STA) zu kurz, um sinnvoll Daten zu übertragen. Insbesondere die sogenannten IEEE 802.11 Beacon-Frames, die in einem Zeitintervall von -100 ms geschickt werden, sind für den Betrieb eines WLAN-Netzwerkes sehr wichtig. Der Betrieb ist nur möglich, wenn eine gewisse Anzahl dieser Frames in den 2 ms Sendepause erfolgreich übertragen wird. Die Wahrscheinlichkeit, dass die Pause jedoch zufällig vom WLAN-AP getroffen wird, ist sehr gering.The second much more critical case is a microwave device with a switching power supply. Here the breaks are significantly shorter. For example, about 8 ms of microwave operation is followed by a short pause of about 2 ms. However, these pauses are too short for some WLAN access points (AP) and WLAN stations (STA) to transmit data in a meaningful way. In particular, the so-called IEEE 802.11 beacon frames, which are sent in a time interval of -100 ms, are very important for the operation of a WLAN network. Operation is only possible if a certain number of these frames are successfully transmitted in the 2 ms transmission pause. However, the probability that the pause will be hit by the WLAN AP is very low.

Hier greift die Erfindung an, die eine adaptive Steuerung der Leistung eines Mikrowellengeräts umfasst, so dass WLAN Betrieb parallel zum Mikrowellenbetrieb zuverlässig erfolgen kann und somit eine Koexistenz gewährleistet wird.This is where the invention comes in, which includes adaptive control of the power of a microwave device, so that WLAN operation can take place reliably in parallel with microwave operation, and thus coexistence is ensured.

Haushaltgeräte mit Mikrowelle nutzen für neue Entwicklungen häufig Schaltnetzteile (Inverter). Ein Grund ist, dass mit solchen Invertern ein Betrieb mit echten Leistungsstufen unterhalb der Maximalleistung des Mikrowellenerzeugers möglich ist, wohingegen trafobasierte Lösungen in der Regel mit einer PWM-artigen Steuerung arbeiten (müssen).Household appliances with microwaves often use switching power supplies (inverters) for new developments. One reason is that with such inverters, operation with real power levels below the maximum power of the microwave generator is possible, whereas transformer-based solutions generally (have to) work with a PWM-type controller.

Ist das Gerät zudem vernetzt, kann es sein, dass die Vernetzungsfunktionen durch die Mikrowelle signifikant beeinträchtigt werden, sofern das gleiche Frequenzband (2.4 GHz) verwendet wird. Eine Alternative wäre die Verwendung von WLAN mit 5 GHz.If the device is also networked, the networking functions may be significantly impaired by the microwave, provided the same frequency band (2.4 GHz) is used. An alternative would be to use 5 GHz WiFi.

Die ursprüngliche Lösung mit einem Trafo-Netzteil hatte technologiebedingt längere Pausen, so dass das Problem dort kaum auftritt. Manche Hersteller von Access Points haben eine Erkennung für Mikrowellen und legen die Beacons gezielt in die Pause von 2 ms, so dass die Störanfälligkeit geringer wird. Hier wird versucht, auf den Störer zu reagieren. Bei vielen Access Points treten jedoch häufiger Probleme auf.The original solution with a transformer power supply had longer breaks due to the technology, so that the problem hardly occurs there. Some manufacturers of access points have a detection for microwaves and specifically place the beacons in the pause of 2 ms, so that the susceptibility to interference is reduced. Here an attempt is made to react to the interferer. However, many access points experience problems more often.

Die Verwendung von 5 GHz-WLAN erfordert eine komplexere Hardware und ist in der Reichweite deutlich eingeschränkt gegenüber 2.4 GHz. Des Weiteren ist die Approbation bei 5 GHz deutlich aufwändiger und teurer.The use of 5 GHz WLAN requires more complex hardware and the range is clearly limited compared to 2.4 GHz. In addition, approval at 5 GHz is significantly more complex and expensive.

Eine Verbesserung über den Access Point kann nur vom Hersteller des Access Points umgesetzt werden. Viele Geräte operieren jedoch normalerweise als WLAN-Station, so dass die Lösung hier nicht funktioniert, da diese auf den Empfang der Beacons angewiesen sind.An improvement via the access point can only be implemented by the manufacturer of the access point. However, many devices normally operate as WLAN stations, so the solution does not work here, since they rely on the reception of the beacons.

Werden diese vom Access Point ungünstig geschickt, kollidieren diese mit dem Mikrowellenbetrieb und können daher nicht empfangen werden. Dies hat einen Verbindungsverlust zur Folge. Zudem muss der Access Point mitunter weitere WLAN-Stationen bedienen und kann sich somit nicht nur nach dem Mikrowellengerät richten.If these are sent unfavorably by the access point, they collide with the microwave mode and can therefore not be received. This results in a loss of connection. In addition, the access point sometimes has to operate other WLAN stations and can therefore not only depend on the microwave oven.

Die der Erfindung zugrundeliegende Aufgabe besteht somit darin, die Beeinträchtigung der Kommunikation in einem Funknetzwerk aufgrund des Betriebs eines Mikrowellengeräts zumindest zu verringern.The object on which the invention is based is therefore to at least reduce the impairment of communication in a radio network due to the operation of a microwave device.

Die Aufgabe wird gelöst durch ein Haushaltsgerät der eingangs genannten Art, wobei die Steuerung des erfindungsgemäßen Haushaltsgeräts dazu eingerichtet ist, in einem Koexistenzmodus die dem Netzteil vorgegebene Leistung für den Betrieb des Magnetrons zeitweise derart zu reduzieren, dass eine Störung der Kommunikation in einem Beacon-Frames verwendenden Funknetzwerk durch die von dem Magnetron erzeugten Mikrowellen reduziert oder verhindert wird.The object is achieved by a household appliance of the type mentioned at the outset, the controller of the household appliance according to the invention being set up to temporarily reduce, in a coexistence mode, the power specified for the power supply for the operation of the magnetron in such a way that a disturbance in the communication in a beacon frame radio network using is reduced or prevented by the microwaves generated by the magnetron.

Die Erfindung macht sich die Erkenntnis zunutze, dass während der temporären Leistungsreduzierung Beacon-Frames übertragen werden können, sodass Störungen in der Kommunikation der sich in dem Funknetzwerk befindenden Geräte verringert oder sogar vermieden werden. Das Haushaltsgerät verwendet einen Koexistenz-Algorithmus, welcher die Kommunikation innerhalb des Funknetzwerkes bei gleichzeitigem Mikrowellenbetrieb erlaubt.The invention makes use of the knowledge that beacon frames can be transmitted during the temporary power reduction, so that interference in the communication of the devices located in the radio network is reduced or even avoided. The household appliance uses a coexistence algorithm which allows communication within the radio network with simultaneous microwave operation.

Wenn das Haushaltsgerät selbst an der Kommunikation über das Funknetzwerk teilnimmt, wird durch die temporäre Leistungsreduzierung die Störung der eigenen Kommunikation verringert oder vermieden. Aufgrund der Leistungsreduzierung kann es zwar zu verringerten Datenraten kommen, diese sind für Hausgeräteanwendungen jedoch ausreichend. Anders als im Stand der Technik wird der Funkbetrieb eines Mikrowellengeräts somit nicht wesentlich durch die Mikrowellen gestört.If the household appliance itself participates in the communication via the radio network, the temporary reduction in performance reduces or prevents the interference in its own communication. The data reduction may result in reduced data rates, but these are sufficient for home appliance applications. Unlike in the prior art, the radio operation of a microwave device is not significantly disturbed by the microwaves.

Die Steuerung des Haushaltsgeräts ist vorzugsweise dazu eingerichtet, die dem Netzteil vorgegebene Leistung für den Betrieb des Magnetrons zeitweise derart zu reduzieren, dass einer WLAN-Station des Funknetzwerks der Empfang von Beacon-Frames ermöglicht wird, welche von einem WLAN-Access Point des Funknetzwerks versendet werden. Das Funknetzwerk kann alternativ zu WLAN auch auf einer anderen 2.4 GHz-Technologie, wie etwa ZigBee oder Bluetooth, basieren. Das Magnetron und das Netzteil sind vorzugsweise Bestandteile eines Hochfrequenzgenerators. Das Magnetron erzeugt vorzugsweise Mikrowellen im 2.4 GHz ISM-Band. Die temporäre Leistungsreduzierung kann auch zu einem temporären Abschalten des Magnetrons führen. Das Netzteil des Haushaltsgeräts ist vorzugsweise ein Schaltnetzteil. Alternativ ist das Netzteil des Haushaltsgeräts ein Trafonetzteil. Die Steuerung des Haushaltsgeräts ist vorzugsweise eine elektronische Steuerungseinrichtung.The control of the household appliance is preferably set up to temporarily reduce the power specified for the power supply for the operation of the magnetron in such a way that a WLAN station of the radio network is able to receive beacon frames which are sent by a WLAN access point of the radio network become. As an alternative to WLAN, the radio network can also be based on another 2.4 GHz technology, such as ZigBee or Bluetooth. The magnetron and the power supply are preferably components of a high-frequency generator. The magnetron preferably generates microwaves in the 2.4 GHz ISM band. The temporary power reduction can also lead to a temporary shutdown of the magnetron. The power supply unit of the household appliance is preferably a Switching power supply. Alternatively, the power supply of the household appliance is a transformer power supply. The control of the household appliance is preferably an electronic control device.

Durch die Erfindung wird die Mikrowelle mit einer Steuerung ausgestattet, die eine Koexistenz mit WLAN oder allgemein auf 2.4 GHz basierenden Technologien (ZigBee, Bluetooth etc.) erlaubt. Diese ist zwar eingeschränkt (Datenrate ist reduziert, aber für Hausgeräteanwendungen noch völlig ausreichend), aber sie ermöglicht eine Kommunikation bei gleichzeitigem Mikrowellenbetrieb. Auch Störungen benachbarter Geräte können reduziert oder je nach benötigter Datenrate ganz verhindert werden.The invention provides the microwave with a controller which allows coexistence with WLAN or technologies based on 2.4 GHz (ZigBee, Bluetooth etc.). This is limited (data rate is reduced, but is still sufficient for home appliance applications), but it enables communication while using the microwave. Interference from neighboring devices can also be reduced or completely prevented depending on the required data rate.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Haushaltsgeräts ist der Koexistenzmodus der Steuerung während des Betriebs des Haushaltsgeräts oder während des Betriebs des Magnetrons durch einen Benutzer aktivierbar. Das Haushaltsgerät kann eine Benutzerschnittstelle zum Aktivieren des Koexistenzmodus der Steuerung durch einen Benutzer aufweisen. Beispielsweise kann das Haushaltsgerät eine Eingabeeinrichtung, beispielsweise einen Touchscreen, aufweisen, über welche der Koexistenzmodus der Steuerung durch eine Benutzereingabe aktivierbar ist. Alternativ oder zusätzlich kann der Koexistenzmodus der Steuerung auch über ein mobiles Endgerät, etwa ein Smartphone, aktivierbar sein, welches signalleitend, beispielsweise über das Funknetzwerk, mit dem Haushaltsgerät verbunden ist. Durch die manuelle Aktivierbarkeit des Koexistenzmodus der Steuerung kann dieser lediglich im Bedarfsfall aktiviert werden, sodass eine Verringerung der Datenrate durch den Koexistenzmodus der Steuerung vermeidbar wird, wenn dieser nicht erforderlich ist. Alternativ kann der Koexistenzmodus der Steuerung während des Betriebs des Haushaltsgeräts oder während des Betriebs des Magnetrons auch dauerhaft aktiviert sein. Durch die automatische Aktivierung des Koexistenzmodus der Steuerung kann eine Störung der Kommunikation über das Funknetzwerk effektiv vermieden werden, ohne das weitere Maßnahmen eines Benutzers erforderlich sind. Ferner kann das Haushaltsgerät dazu eingerichtet sein, den Koexistenzmodus der Steuerung selbsttätig zu aktivieren, wenn eine Notwendigkeit der Einstellung des Koexistenzmodus der Steuerung zur Vermeidung einer Störung der Kommunikation in dem Funknetzwerk durch das Haushaltsgerät erkannt wird. Die Notwendigkeit der Einstellung des Koexistenzmodus der Steuerung zur Vermeidung einer Störung kann beispielsweise bei der Detektion von Kommunikation über das Funknetzwerk erkannt werden. Somit kommt es zu einer automatischen und bedarfsgerechten Einschaltung Koexistenzmodus der Steuerung des Haushaltsgeräts.In a preferred embodiment of the household appliance according to the invention, the coexistence mode of the control can be activated by a user during the operation of the household appliance or during the operation of the magnetron. The household appliance can have a user interface for activating the coexistence mode of the control by a user. For example, the household appliance can have an input device, for example a touchscreen, via which the coexistence mode of the control can be activated by a user input. As an alternative or in addition, the coexistence mode of the control can also be activated via a mobile terminal, for example a smartphone, which is connected to the household appliance in a signal-conducting manner, for example via the radio network. Due to the manual activation of the coexistence mode of the controller, it can only be activated if necessary, so that a reduction in the data rate through the coexistence mode of the controller can be avoided if it is not required. Alternatively, the coexistence mode of the control can also be permanently activated during the operation of the household appliance or during the operation of the magnetron. By automatically activating the coexistence mode of the control, a disruption of the communication via the radio network can be effectively avoided without further action by a user being required. Furthermore, the household appliance can be set up to automatically activate the coexistence mode of the controller if a need to set the coexistence mode of the controller to avoid interference with communication in the radio network by the household appliance is recognized. The necessity of setting the coexistence mode of the control in order to avoid a disturbance can be recognized, for example, when detecting communication over the radio network. This results in an automatic and demand-based activation of the coexistence mode of the control of the household appliance.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Haushaltsgeräts ist die Steuerung dazu eingerichtet, in dem Koexistenzmodus in mehreren zeitlich beabstandeten Zeitfenstern die dem Netzteil vorgegebene Leistung für den Betrieb des Magnetrons zu reduzieren. Innerhalb der Zeitfenster können dann beispielsweise die Beacon-Frames über das Funknetzwerk übertragen werden. Durch die Übertragung der Beacon-Frames innerhalb der Zeitfenster, in welchen die Leistung für den Betrieb des Magnetrons reduziert ist, kann dann eine Kommunikationsverbindung einer oder mehrerer Geräte zu dem Funknetzwerk aufrechterhalten werden. Ferner kann innerhalb der Zeitfenster eine Kommunikation über das Funknetzwerk erfolgen. Die Zeitspannen zwischen den Zeitfenstern können konstant oder variabel sein. Die Zeitspannen zwischen den Zeitfenstern können beispielsweise im Millisekundenbereich liegen. Ferner können die zeitlich beabstandeten Zeitfenster eine konstante oder eine variable Zeitdauer haben. Die Zeitdauer der Zeitfenster kann beispielsweise im Millisekundenbereich liegen.In a further preferred embodiment of the household appliance according to the invention, the controller is set up to supply the power specified for the power supply for the operation of the magnetron in the coexistence mode in several time-spaced time windows to reduce. The beacon frames can then be transmitted over the radio network within the time window, for example. The communication of one or more devices to the radio network can then be maintained by transmitting the beacon frames within the time window in which the power for operating the magnetron is reduced. Furthermore, communication can take place within the time window via the radio network. The time spans between the time windows can be constant or variable. The time spans between the time windows can be in the millisecond range, for example. Furthermore, the time-spaced time windows can have a constant or a variable time period. The time period of the time window can be in the millisecond range, for example.

Es ist außerdem ein erfindungsgemäßes Haushaltsgerät vorteilhaft, bei welchem die Steuerung dazu eingerichtet ist, in dem Koexistenzmodus die zeitlich beabstandeten Zeitfenster und/oder die Zeitspannen zwischen den Zeitfenstern mit einem Zufallszeitfenster zu überlagern. Die Zufallszeitfenster können positiv oder negativ sein, sodass die zeitlich beabstandeten Zeitfenster und/oder die Zeitspannen zwischen den Zeitfenstern durch die Überlagerung verlängert oder verkürzt werden können. Die Zufallszeitfenster können im Millisekundenbereich liegen. Durch die Überlagerung mit einem Zufallszeitfenster wird die Quote erfolgreich übertragener Beacon-Frames und die Quote erfolgreich übertragener regulärer Pakete signifikant erhöht. Die zeitlich beabstandeten Zeitfenster, die Zeitspannen zwischen den Zeitfenstern, das Zufallszeitfenster und/oder die Leistungsreduzierung sind derart konfigurierbar, dass diese auf unterschiedliche Gerätetypen und verschiedene Funknetzwerke angepasst werden können. Die Konfiguration kann dabei manuell durch einen Benutzer erfolgen. Die Konfiguration kann beispielsweise über ein Userinterface des Haushaltsgeräts erfolgen. Alternativ oder zusätzlich kann das Haushaltsgerät dazu eingerichtet sein, einen Konfigurationsdatensatz von einer Datenbank abzurufen und die Konfiguration auf Basis des Konfigurationsdatensatzes selbsttätig auszuführen. Beispielsweise erlaubt das Haushaltsgerät die Einstellung eines WLAN-Koexistenzmodus, eines Bluetooth-Koexistenzmodus und/oder eines ZigBee-Koexistenzmodus.A household appliance according to the invention is also advantageous, in which the controller is set up to overlay the time-spaced time windows and / or the time spans between the time windows with a random time window in the coexistence mode. The random time windows can be positive or negative, so that the temporally spaced time windows and / or the time periods between the time windows can be lengthened or shortened by the overlay. The random time windows can be in the millisecond range. The overlay with a random time window significantly increases the rate of successfully transmitted beacon frames and the rate of successfully transmitted regular packets. The time-spaced time windows, the time spans between the time windows, the random time window and / or the power reduction can be configured in such a way that they can be adapted to different device types and different radio networks. The configuration can be done manually by a user. The configuration can take place, for example, via a user interface of the household appliance. Alternatively or additionally, the household appliance can be set up to retrieve a configuration data record from a database and to carry out the configuration automatically on the basis of the configuration data record. For example, the household appliance allows the setting of a WLAN coexistence mode, a Bluetooth coexistence mode and / or a ZigBee coexistence mode.

In einer weiteren vorteilhaften Ausführungsform weist das erfindungsgemäße Haushaltsgerät ein Funkmodul zur Kommunikation über das Kommunikationsnetzwerk auf. Die Steuerung des Haushaltsgeräts ist vorzugsweise dazu eingerichtet, in dem Koexistenzmodus die dem Netzteil vorgegebene Leistung für den Betrieb des Magnetrons zeitweise derart zu reduzieren, dass dem Funkmodul während des Betriebs des Magnetrons der Empfang von Beacon-Frames aus dem Funknetzwerk ermöglicht wird. Dadurch, dass dem Funkmodul während des Betriebs des Magnetrons der Empfang von Beacon-Frames aus dem Funknetzwerk ermöglicht wird, kann die Verbindung des Haushaltsgeräts zu dem Funknetzwerk gewährleistet werden. Das Risiko von Verbindungsunterbrechungen oder Kommunikationsproblemen wird somit erheblich reduziert. Das Funkmodul ist beispielsweise ein WLAN-Modul.In a further advantageous embodiment, the household appliance according to the invention has a radio module for communication via the communication network. The controller of the household appliance is preferably set up to temporarily reduce the power specified for the power supply for the operation of the magnetron in the coexistence mode in such a way that the radio module is able to receive beacon frames from the radio network while the magnetron is operating. The fact that the radio module is able to receive beacon frames from the radio network while the magnetron is in operation enables the connection of the household appliance to the radio network. The risk of Interruptions in connection or communication problems are thus significantly reduced. The radio module is, for example, a WLAN module.

In einer Weiterbildung des erfindungsgemäßen Haushaltsgeräts ist die Steuerung dazu eingerichtet, einen Verbindungsverlust des Funkmoduls zu dem Funknetzwerk festzustellen und die dem Netzteil vorgegebene Leistung für den Betrieb des Magnetrons nach der Feststellung des Verbindungsverlusts zeitweise derart zu reduzieren, dass die Verbindung des Funkmoduls zu dem Funknetzwerk wiederhergestellt wird. Durch diese Steuerungsroutine wird ein Feedback-Kanal umgesetzt, mit welchem die Kommunikationsfähigkeit des Haushaltsgeräts in dem Funknetzwerk überwachbar und, falls erforderlich, wiederherstellbar ist. Beispielsweise kann durch die Steuerungsroutine festgestellt werden, dass die Zeitfenster, in welchen die Leistung für den Betrieb des Magnetrons reduziert ist, zu klein sind, um eine störungsfreie Kommunikation umsetzen zu können. In diesem Fall können die Zeitfenster, in welchen die Leistung für den Betrieb des Magnetrons reduziert ist, vergrößert werden. Alternativ oder zusätzlich kann durch die Steuerungsroutine festgestellt werden, dass die Zeitspannen zwischen den Zeitfenstern, in welchen die Leistung für den Betrieb des Magnetrons nicht reduziert ist, zu lang sind, um eine störungsfreie Kommunikation umsetzen zu können. In diesem Fall können die Zeitspannen, in welchen die Leistung für den Betrieb des Magnetrons nicht reduziert ist, verkürzt werden. Alternativ oder zusätzlich kann durch die Steuerungsroutine festgestellt werden, dass die Reduzierung der Leistung für den Betrieb des Magnetrons während der Zeitfenster nicht ausreichend ist, um eine störungsfreie Kommunikation umsetzen zu können. In diesem Fall kann die Reduzierung der Leistung für den Betrieb des Magnetrons während der Zeitfenster intensiviert werden.In a development of the household appliance according to the invention, the controller is set up to determine a loss of connection of the radio module to the radio network and to temporarily reduce the power given to the power supply for the operation of the magnetron after the connection loss has been determined in such a way that the connection of the radio module to the radio network is restored becomes. This control routine implements a feedback channel with which the communication capability of the household appliance in the radio network can be monitored and, if necessary, restored. For example, the control routine can determine that the time windows in which the power for operating the magnetron is reduced are too small to be able to implement interference-free communication. In this case, the time windows in which the power for operating the magnetron is reduced can be increased. Alternatively or additionally, the control routine can determine that the time spans between the time windows in which the power for the operation of the magnetron is not reduced are too long to be able to implement interference-free communication. In this case, the time periods in which the power for the operation of the magnetron is not reduced can be shortened. Alternatively or additionally, the control routine can determine that the reduction in power for the operation of the magnetron during the time window is not sufficient to be able to implement interference-free communication. In this case, the reduction in power for the operation of the magnetron can be intensified during the time window.

In einer anderen bevorzugten Ausführungsform ist das erfindungsgemäße Haushaltsgerät ein Solo-Mikrowellengerät oder ein Mikrowellengerät mit zusätzlicher Backofen- oder Dampfgarfunktion.In another preferred embodiment, the household appliance according to the invention is a solo microwave appliance or a microwave appliance with an additional oven or steam cooking function.

Die der Erfindung zugrundeliegende Aufgabe wird ferner durch ein Verfahren der eingangs genannten Art gelöst, wobei im Rahmen des erfindungsgemäßen Verfahrens ein zeitweises Reduzieren der Leistung für den Betrieb des Magnetrons in einem Koexistenzmodus der Steuerung erfolgt, sodass eine Störung der Kommunikation in einem Beacon-Frames verwendenden Funknetzwerk durch die von dem Magnetron erzeugten Mikrowellen reduziert oder verhindert wird. Das Verfahren wird vorzugsweise zum Steuern des Betriebs eines Haushaltsgeräts nach einer der vorstehend beschriebenen Ausführungsformen ausgeführt. Hinsichtlich der Vorteile und Modifikationen des erfindungsgemäßen Verfahrens wird somit zunächst auf die Vorteile und Modifikationen des erfindungsgemäßen Haushaltsgeräts verweisen.The object on which the invention is based is further achieved by a method of the type mentioned at the outset, with the method according to the invention temporarily reducing the power for operating the magnetron in a coexistence mode of the control, so that communication in a beacon frame is disrupted Radio network is reduced or prevented by the microwaves generated by the magnetron. The method is preferably carried out for controlling the operation of a household appliance according to one of the above-described embodiments. With regard to the advantages and modifications of the method according to the invention, reference is therefore first made to the advantages and modifications of the household appliance according to the invention.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens erfolgt ein selbsttätiges Aktivieren des Koexistenzmodus der Steuerung durch das Haushaltsgerät bei dessen Einschaltung. Alternativ wird der Koexistenzmodus der Steuerung während des Betriebs des Haushaltsgeräts oder während des Betriebs des Magnetrons durch einen Benutzer aktiviert. Ferner kann der Koexistenzmodus der Steuerung des Haushaltsgeräts bei der Erfassung einer Notwendigkeit der Einstellung des Koexistenzmodus der Steuerung zur Vermeidung einer Störung der Kommunikation in dem Funknetzwerk durch das Haushaltsgerät selbsttätig aktiviert werden.In a preferred embodiment of the method according to the invention, the coexistence mode of the control is automatically activated by the household appliance when it is switched on. Alternatively, the coexistence mode of the controller is activated by a user during the operation of the household appliance or during the operation of the magnetron. Furthermore, the coexistence mode of the control of the household appliance can be activated automatically when the home appliance detects a need to set the coexistence mode of the control to avoid interference with communication in the radio network.

In einer Weiterbildung des erfindungsgemäßen Verfahrens erfolgt das zeitweise Reduzieren der Leistung für den Betrieb des Magnetrons in dem Koexistenzmodus der Steuerung durch das Reduzieren der Leistung für den Betrieb des Magnetrons während mehrerer zeitlich beabstandeter Zeitfenster, wobei die zeitlich beabstandeten Zeitfenster und/oder die Zeitspannen zwischen den Zeitfenstern vorzugsweise mit einem Zufallszeitfenster überlagert werden.In a development of the method according to the invention, the power for the operation of the magnetron is temporarily reduced in the coexistence mode of the control by reducing the power for the operation of the magnetron during several time-spaced time windows, the time-spaced time windows and / or the time periods between the Time windows are preferably overlaid with a random time window.

Nachfolgend werden bevorzugte Ausführungsformen der Erfindung unter Bezugnahme auf die beiliegenden Zeichnungen näher erläutert und beschrieben. Dabei zeigen:

Preferred embodiments of the invention are explained and described in more detail below with reference to the accompanying drawings. Show:
Fig. 1
an embodiment of the household appliance according to the invention in a schematic representation; and
Fig. 2
the course of the power given to the power supply for the operation of the magnetron in a schematic representation.

Die Fig. 1 zeigt ein Haushaltsgerät 10, welches beispielsweise ein Solo-Mikrowellengerät oder ein Mikrowellengerät mit zusätzlicher Backofen- oder Dampfgarfunktion sein kann.The Fig. 1 shows a household appliance 10, which can be, for example, a solo microwave appliance or a microwave appliance with an additional oven or steam cooking function.

Das Haushaltsgerät 10 umfasst ein Magnetron 12, ein Netzteil 16 und eine Steuerung 18. Das Magnetron 12 ist dazu eingerichtet, im Betrieb Mikrowellen 14 im 2.4 GHz ISM-Band zu erzeugen. Die Steuerung 18 des Haushaltsgeräts 10 gibt dem als Schaltnetzteil ausgebildeten Netzteil 16 die Leistung vor, mit der das Magnetron 12 betrieben werden soll.The household appliance 10 comprises a magnetron 12, a power supply unit 16 and a controller 18. The magnetron 12 is set up to generate microwaves 14 in the 2.4 GHz ISM band during operation. The controller 18 of the household appliance 10 specifies the power, with which the magnetron 12 is to be operated, to the power supply unit 16 designed as a switching power supply.

Die Steuerung 18 beinhaltet einen Koexistenz-Algorithmus 20. Der Koexistenz-Algorithmus 20 wird bei Notwendigkeit oder manuell durch einen Benutzer aktiviert. Alternativ kann der Koexistenz-Algorithmus 20 auch standardmäßig aktiviert sein. Der Koexistenz-Algorithmus 20 sorgt dafür, dass die Mikrowellenleistung P zeitweise reduziert bzw. gezielt so abgeschaltet wird, dass ein WLAN-Access Point eines Funknetzwerkes mit einer gewissen Wahrscheinlichkeit in der Lage ist, Beacon-Frames erfolgreich zu versenden und ein anderes Gerät in dem als WLAN-Netzwerk ausgebildeten Funknetzwerk die versendeten Beacon-Frames trotz der von dem Magnetron 12 erzeugten Mikrowellen 14 empfängt. Das Funknetzwerk kann alternativ zu WLAN auch auf einer anderen 2.4 GHz-Technologie, wie etwa ZigBee oder Bluetooth, basieren.The controller 18 includes a coexistence algorithm 20. The coexistence algorithm 20 is activated if necessary or manually by a user. Alternatively, the coexistence algorithm 20 can also be activated by default. The coexistence algorithm 20 ensures that the microwave power P is temporarily reduced or specifically switched off in such a way that a WLAN access point of a radio network with a certain Probability is able to successfully send beacon frames and another device in the radio network designed as a WLAN network receives the sent beacon frames despite the microwaves 14 generated by the magnetron 12. As an alternative to WLAN, the radio network can also be based on another 2.4 GHz technology, such as ZigBee or Bluetooth.

Durch die temporäre Leistungsreduzierung werden somit Störungen in der Kommunikation der Geräte in dem Funknetzwerk verringert oder vermieden. Der Koexistenz-Algorithmus 20 erlaubt also die Kommunikation innerhalb des Funknetzwerkes bei gleichzeitigem Mikrowellenbetrieb.The temporary power reduction thus reduces or prevents interference in the communication of the devices in the radio network. The coexistence algorithm 20 thus allows communication within the radio network with simultaneous microwave operation.

Das Haushaltsgerät 10 umfasst ferner ein Funkmodul 22, mittels welchem das Haushaltsgerät 10 selbst über das Funknetzwerk mit anderen Geräten kommunizieren kann. Das Funkmodul 22 ist vorliegend als WLAN-Modul ausgebildet. Die Steuerung 18 ist dazu eingerichtet, in dem Koexistenzmodus, in welchem der Koexistenz-Algorithmus 20 eingesetzt wird, die dem Netzteil 16 vorgegebene Leistung P für den Betrieb des Magnetrons 12 zeitweise derart zu reduzieren, dass dem Funkmodul 22 während des Betriebs des Magnetrons 12 der Empfang von Beacon-Frames aus dem Funknetzwerk ermöglicht wird. Durch den Koexistenz-Algorithmus 20 verringert oder vermeidet das Haushaltsgerät 10 eine durch die Mikrowellen 14 verursachte Störung der eigenen Kommunikation.The household appliance 10 further comprises a radio module 22, by means of which the household appliance 10 itself can communicate with other devices via the radio network. In the present case, the radio module 22 is designed as a WLAN module. In the coexistence mode in which the coexistence algorithm 20 is used, the controller 18 is set up to temporarily reduce the power P given to the power supply unit 16 for the operation of the magnetron 12 in such a way that the radio module 22 during the operation of the magnetron 12 Reception of beacon frames from the radio network is made possible. The coexistence algorithm 20 reduces or prevents the domestic appliance 10 from interfering with its own communication caused by the microwaves 14.

Außerdem ist die Steuerung 18 dazu eingerichtet, über den Feedback-Kanal 24 einen Verbindungsverlust des Funkmoduls 22 zu dem Funknetzwerk festzustellen und die dem Netzteil 16 vorgegebene Leistung P für den Betrieb des Magnetrons 12 nach der Feststellung des Verbindungsverlusts zeitweise derart zu reduzieren, dass die Verbindung des Funkmoduls 22 zu dem Funknetzwerk wiederhergestellt wird.In addition, the controller 18 is set up to determine via the feedback channel 24 that the radio module 22 has lost a connection to the radio network and to temporarily reduce the power P given to the power supply unit 16 for the operation of the magnetron 12 after the connection loss has been determined in such a way that the connection of the radio module 22 is restored to the radio network.

Die Fig. 2 zeigt die zeitweise Leistungsreduzierung durch den Koexistenz-Algorithmus 20. Die Leistung P ist über die Zeit t aufgetragen. Der Koexistenzmodus der Steuerung 18 ist zwischen den Zeitpunkten t0 und t1 aktiviert, sodass in dieser Zeit der Koexistenz-Algorithmus 20 angewandt wird.The Fig. 2 shows the temporary power reduction by the coexistence algorithm 20. The power P is plotted over time t. The coexistence mode of the controller 18 is activated between the times t 0 and t 1 , so that the coexistence algorithm 20 is used during this time.

Hierbei wird die Leistung P für den Betrieb des Magnetrons 12 während mehrerer zeitlich beabstandeter Zeitfenster Y auf ein Leistungsniveau Z reduziert. Die zeitlich beabstandeten Zeitfenster Y und/oder die Zeitspannen X zwischen den Zeitfenstern Y können von einem nicht dargestellten Zufallszeitfenster überlagert werden. Die Zufallszeitfenster können positiv oder negativ sein, sodass die zeitlich beabstandeten Zeitfenster Y und/oder die Zeitspannen X zwischen den Zeitfenstern Y durch die Überlagerung verlängert oder verkürzt werden können. Hierdurch kann die Quote erfolgreich übertragener Beacons und regulärer Pakete signifikant erhöht werden.Here, the power P for the operation of the magnetron 12 is reduced to a power level Z during a plurality of time slots Y spaced apart from one another in time. The time-spaced time windows Y and / or the time periods X between the time windows Y can be overlaid by a random time window, not shown. The random time windows can be positive or negative, so that the time-spaced time windows Y and / or the time periods X between the time windows Y can be lengthened or shortened by the overlay. This can significantly increase the rate of successfully transmitted beacons and regular packets.

Die Zeitspannen X zwischen den Zeitfenstern Y, die Zeitfenster Y, das Niveau der reduzierten Leistung Z und die überlagerbaren Zufallszeitfenster sind konfigurierbar, so dass diese auf unterschiedliche Gerätetypen und verschiedene Funknetzwerke angepasst werden können. Optional ist es möglich, die verschiedenen Modi über ein Userinterface (UI) des Haushaltsgeräts 10 zu konfigurieren. Beispielsweise kann auf diese Weise ein WLAN-Koexistenzmodus, Bluetooth-Koexistenzmodus oder ein ZigBee-Koexistenzmodus eingestellt werden.The time periods X between the time windows Y, the time windows Y, the level of the reduced power Z and the superimposable random time windows are configurable, so that they can be adapted to different device types and different radio networks. It is optionally possible to configure the different modes via a user interface (UI) of the household appliance 10. For example, a WLAN coexistence mode, Bluetooth coexistence mode or a ZigBee coexistence mode can be set in this way.
